Best oil cooler and temp difference????

[DAVID GAGNARD]

Curt;

My race motor makes 472 fwhp and I normally shift at 6,000rpms, with a 7,000 rpm chip in the MSD box.......I do not run a high volume pump, I run a Melling HP oil pump, it can be adjusted for the oil pressure, but is standard volume......I think high volume oil pumps are hard on the cam/distibutor gears and are not always needed.......A very well know race shop told me that they never use high volume pumps on any race motor much less a street motor, but they do like the HP model oil pumps.........

Synthetic oil can and will tolerate more heat, but after a certain temp, I'd guess over 230 or so, your oil is so hot it's not doing the job it was meant for........

My race motor is a 331 cu.in. stroker based on a 302 block using the Chevy rods, smaller journals than the ford 302.......my street car has a 351-W and the main crank journals are 3" diameter, very large and produce a lot of heat compared to the smaller 2.25" 302 main journals..... I have done some track time with the street car/351-W and have seen 240 to 250 oil temps on a 100 degree day, both motors have road race baffled pans and windage trays.....
